C/2011
L4 (Panstarrs) is a non-periodic comet discovered in June 2011
by the Pan-Starrs telescope. Before perihelion in 2013
March it put on a fine show in the western sky for Southern
Hemisphere observers as it continued its journey north. It is believed to be
very young and it is uncertain whether it will return to the inner solar system.
